What is the angle between hour and minute hand at $2:15\mathrm{pm}$ in a watch ?

A $50 \mathrm{cm}$ long pendulum makes an arc of $16 \mathrm{cm}$ when it oscillates. Then what will be the angle formed?

A railway track is to be formed according to a circle. If a change of $40 \mathrm{m}$ distance is to be made in that track at $25°$ of if's direction then the radius of that track will be keep equal to

A wheel makes $3.5$ revolutions in one second. Time taken by wheel to revolve an angle of $55$ radian is

The radian measure of $63°{14}^{\text{'}}{51}^{\text{'}\text{'}}$ is

In a triangle $ABC, ABC, AB=AC . BA$ is produced to $D$ in such a way that $AC=AD$. Then circular measure of $\angle BCD$ is

Two angles of a triangle are $\frac{1}{2}$ rad and $\frac{1}{3}\mathrm{rad}$.Then measure of the $3$ rd angle in degree is $\left(\pi =\frac{22}{7}\right)$
